DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 477,739, dated June 28,1892.

Application filed June 29, 1891. Serial No. 397,831. (No model.)

To all whom it may concern: 1

Be it known that I, AUGUST G. DAHMER, of Alameda, in the county ofAlameda and State of California, have invented a new and usefulImprovement in Hangers, of which the following is a full, clear, andexact description.

My invention relates to animprovement in hangers, especially that classof hangers adapted for use in connection with sliding doors.

The object of the invention is to providea hanger of simple, durable,and economic construction wherebya door may be expeditiously andconveniently raised or lowered, as occasion may demand,and wherein asingle track only will be necessary for the hanger or hangers toslideupon.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in both the news.

Figure 1 is a side elevation of the improved hanger, partly in section;and Fig. 2 is a vertical section taken practically 011 the line no at ofFig. 1, and also showing the track.

The device consists, primarily, of a suspension-frame A, a hanger B, andan adjusting mechanism 0. The suspension-frame com,-

prises two uprights and 11, a rear crossbar 12, thinner than theuprights, and a sill 13, preferably of a greater length than the widthof the body portion of the frame, which sill, at or near its center, ispreferably provided upon its under surface with a dovetail tongue 14..The suspension-frame is provided with a central vertical opening 15. Theopening extends through the top of the frame in front of the uppercross-bar 12, and the frame is provided with two opposite verticalslideways 16. (Shown in dotted lines, Fig. 1, and in positive lines,Fig. 2.) The opening at one side of the frame is rectangular, as shownat min Fig. 2, and the opening at the opposite side contains at thebottom thereof a shoe 17 the said shoe resting upon the sill 13 andhaving an inclined upper face. In one of the uprights a recess 18 isproduced above the lower portion of the shoe 17, and the recessed end ofthe upright is made to extend downward and engage with the inclinedsurface of the shoe at its lower end. The shoe 17 is of less thicknessthan the depth of the opening 15, and the opening is adapted toaccommodzttethe hanger B. This hanger consists of a vertical plate 19,provided with tongues 20 atits sides, which tongues slide in the grooves16 of the suspension-frame A, and an angular arm 21, essentiallyinverted-L shape in cross-section, is attached to the upper frontportion of the plate 19, the vertical member of the arm being of muchless length than that .of the plate. By reason of thearm 21 forming aportion of the hanger one member of the hanger is spaced some distancefrom the front of the suspension-frame. Between the Vertical member ofthe angular extension 21 of the hanger and the plate 19 a periphor-'ally-grooved Wheel 22 is pivoted, and in the bottom portion of thevertical member of the hanger a recess 23 is made in the front face,extending through from side to side and to the bottom, and in therecessed portion of the plate a transverse elongated slot 2 1 isproduced. The recess 23 in the hanger produces in the vertical member 19thereof a transverse shoulder 25, and between the shoulder 25 and theinclined face of the shoe 17 and in engagement with both an adjusting-block 26 is held to slide, the upper face of the block be ingstraight as it engages with the shoulder 25 of the hanger, and the lowerface is 111- clined to travelupon the inclined face of the shoe. Theblock 26 is provided with a threaded bore 28, leading through from sideto side. The block is manipulated through the medium of an adjusting-screw 29, which passes diagonally through the suspensiomframe andthrough the bore of the block. The lower end of the screw is providedwith a head 30, and the upper end has preferably swiveled thereon a cap31, whereby the screw may be revolved to move the block without movingfrom a fixed position.

In a housing D, located above the door E, a rail 32 is horizontallysecured in any suit able or approved manner, which rail has at taohedthereto a track 33, upon which the wheel 22 of the device travels. Theblock 26 has formed integral with or projected from its rear side a stud34,whicl1 travels in the transverse slot24= of the hanger B, and uponthe front face of the block a friction-wheel 35 is pivoted, its positionbeing such that it is below the track 33 and acts to prevent the Wheelfrom jumping the track.

Upon the top of the door E a rail 36 is or-e dinarily secured, and saidrail is provided with a dovetail slot 37 to receive the dovetailprojection or rib upon the sill 13 of the device. By this means the dooris expeditiously and conveniently connected with the device, and it Willbe observed that a bottom rail or track is not required, as the door issuspended from the single track 33.

Any desired number of hangers or hanging devices may be employed infitting upa door;

It is evident thatby manipulating the screw- 29 in onedirection theblock 26 will be made:

the adjusting-screw is loosely mounted in the:

suspension frame, but passes through a. threaded aperture in the block.Thus unless the adjusting-screw is purposely turned the block willremain stationary.

Having thus described my invention, I: claim as new and desire to secureby Letters Patent 1. In a hanging device for hanging doors and for likepurposes, the combination, with a suspension-frame provided with anopening having an inclined plane at its bottom, of a hanger upon whichthe suspension-frame has sliding movement, provided with a shoulder nearits lower end and a transverse slot near the shoulder, a wedge-blockadapted to travel in engagement with the inclined plane of the frame andthe shoulder of the hanger and having a stud projection extendingthrough the slot in the hanger, and an adjusting-screw regulating themovements of the wedge-block to raise and lower the suspension-frame, asand for the purpose specified.

2. In a hanging device for doors and for.

like purposes, the combination, with a susheld to slide in engagementwith thehanger and the inclined plane, an adj Listing-screw turning inthe frame and passing through the bore in the block, an extension fromthe block passed through the slot in the hanger, and a friction-Wheelcarried by the block, as and for the purpose specified.
